Section 8.10.5 9a specifies that a property descriptor cannot both have
accessors and specify the writability of the property. The previous
error message was misleading because it referred to writable rather
than specifying the writability (which includes writable: false).

Since https://codereview.chromium.org/366103005 the promise tests null out
various globals, to ensure the promise implementation doesn’t itself rely
on functions patchable by monkeys.
Unfortunately, doing so breaks test assertion failures which rely on
those globals.
This isn’t the ideal solution, but does improve the current state.

NumberFormat previously just used a min of 0 digits after the decimal and a max of 3. This CL changes it so that we use the ICU currency data, and set the min and max to the number of numbers after the decimal point for each currency.
This CL also fixes a small bug where if the minimum fraction digits is above 3 but the maximum fraction digits isn't set, then it returns with only three numbers after the decimal point.

The modified assertions targeted the property descriptor for the
template object's first "cooked" value. The code immediately preceeding
these statements asserts these values.
Update the assertions to instead target the property descriptor for the
template object's first "raw" value (which are otherwise untested).

edit1: adding jochen to reviewers since he was assigned through the issue tracker and danno since he seems to do a fair amount of cross-platform work
edit2: removing BUG reference because I don't understand what LOG needs to contain (and it seems to link to chromium and not the v8 repo). Please edit commit message as appropriate.

Currently the derived type of a right shift does not narrow the input
type based on the actual shift amount - well it does some narrowing
but more can be down. For patterns such as u32[i>>2], which is very
common is asm.js code, this limits the ability to later prove that an
index bounds check is unnecessary which can have a significant
performance impact.

- All the added authors have signed the CLA.
- Updated 2 AUTHORS lines to match the e-mail addresses used for signing the CLA.
- In addition, checked that all authors in the AUTHORS file after this change
have signed the CLA.
- Whenever it was possible to guess, based on the e-mail address, that the
contribution was made under a corporate CLA, added the company and the
wildcard instead of the individual.

Updating AUTHORS for companies who have signed CCLA.
Changes:
- Added wildcard rules for company e-mail addresses
- Removed individual e-mail addresses for contributors who are under a corporate
CLLA (the copyright holder in this case is the company, not the individual
authors). Domains affected by this change: intel.com, arm.com, codeaurora.org.
In addition, added a wildcard rule for Chromium (which was not previously
listed at all).

The first jump to a specific label was marked as jump to absolute
position -4. This value was stored in the assembly as a branch to a
offset (-4 - (instruction offset + 8)). The offset is only 24 bit
long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow
the offset.
Fix by denoting the first jump to a label by storing the jump
instruction location as the target. This will result in offset of -8,
which of course always fits in the branch instruction.

Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.
* V8::CancelTerminateExecution() -- When execution is terminated via a call
to V8::TerminateExecution(), this method can be called to clear the
termination exception so that the engine can continue to be used.
* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
exception, HasTerminated() will return true to indicate it is valid to
call V8::ResumeExecution() if desired.
A test case is added to cctest/test-thread-termination.cc.
